The lip sync is pretty good I just have a few small notes.
-The translation on the mouth control at the start is a little too much
-The end of "Easy", try showing the last shape a little longer and scaling smaller into the default smile before going back into that "EE" in "even" (I think that will smooth that transition more)

As for the rest of the face I have just a few more thoughts.
-Eyes: stay longer on eye dart. Don't go overboard with the amount of microdarts and don't go just left and right, otherwise it looks a little like he is reading an autoque.
-Then some of the head moves and brow moves feel a little 'twitchy'. Just give them a little more time and overshoots etc.

I'm sorry but I don't see any lip Sync. Maybe you got an export problem. You may want to Edit your submission using the Edit button at the top right of this page. Or if not go to your profile under the exercise submissions page.
